camera clipping plane?

 From:  rhodesy

I have a scene that i have been messing around with the units in when testing importing PDFs - which now works great. Im working in mm so the scene is quite large compared to the moi default so i have adjusted the grid to show every 100mm. However when i zoom in there appears to be a camera clipping plane that cuts through the object as i move closer and hides it to the camera. Is there a way to reset the camera so this doesn't happen? Ive tried saving and restarting moi but that didn't work.

Cheers for any help on this.......also good to know i can import clean dwgs (via archicad and saving as a PDF - also curves are recognised! Bonus!) Just need that layer system now!!!
